Features & Benefits
- Synchronizes with standard telecom system references and synthesizes a wide variety of protected telecom line interface clocks that are compliant with Telcordia GR-253-CORE and ITU-T G.813
- Internal APLL provides standard output clock frequencies up to 622.08 MHz with jitter < 3 ps RMS suitable for GR-253-CORE OC-12 and G.813 STM-16 interfaces
- Programmable output synthesizer generates clock frequencies from any multiple of 8 kHz up to 77.76 MHz in addition to 2 kHz
- Provides 3 reference inputs which support clock frequencies with any multiples of 8 kHz up to 77.76 MHz in addition to 2 kHz
- Digital Phase Locked-Loop (DPLL) provides all the features necessary for generating SONET/SDH compliant clocks including automatic hitless reference switching, automatic mode selection (locked, free-run, holdover), and selectable loop bandwidth
- Generates several styles of output frame pulses with selectable pulse width, polarity, and frequency
